My 1964 Breitling Navitimer, got it for nothing 15 years ago, as it wasn't working, spent a few hundred quid getting it repaired and hasn't missed a beat since. Made me feel old a few months back though, a girl a bit younger than me who I was going out with asked why I fiddled with my watch every morning, she just couldn't get her head round the fact that watches didn't always have batteries .
